For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0030] like Figures 1 to 6 As shown, the rolling device includes: a rolling body 10, a mounting body 20, a rolling scraper 30, and a driving assembly 40;

[0031] The mounting body 20 is rotatably connected to the rolling body 10, the rolling scraper 30 is detachably connected to the mounting body 20, the driving assembly 40 is connected to the rolling body 10, and a first driving member 201 is fixed on the mounting body 20, the driving assembly 40 is connected to the second driving member 401, and the first driving member 201 cooperates with the second driving member 401; when the driving assembly 40 is running, the driving assembly 40 drives the second driving member 401 to move, so that the second driving member 401 drives the first driving member 201 to move, so that the mounting body 20 rotates relative to the rolling body 10 to adjust the position of the rolling scraper 30.

[0032] In the embodiment of the present application, since the mounting body 20 is rotatably connected to the rolling body 10, and the rolling scraper 30 is detachably connected to the mounting body 20, the mounting body 20 is rotatable relative to the rolling body 10, and when the mounting body 20 rotates relative to the rolling body 10, the rolling scraper 30 is driven to rotate, and the position of the rolling scraper 30 is adjusted. Since the driving assembly 40 is connected to the rolling body 10, and the first driving member 201 is fixed on the mounting body 20, the driving assembly 40 is connected to the second driving member 401, and the first driving member 201 cooperates with the second driving member 401, once the driving assembly 40 is running, the driving assembly 40 can drive the second driving member 401 to move, so that the second driving member 401 drives the first driving member 201 to move, so that the first driving member 201 drives the mounting body 20 to rotate relative to the rolling body 10, and the mounting body 20 drives the rolling scraper 30 to move, and the position of the rolling scraper 30 is adjusted. That is, in the embodiment of the present application, by providing a driving component 40, and the driving component 40 is connected to the second driving member 401, and the mounting body 20 is connected to the first driving member 201, the driving component 40 can drive the second driving member 401 to move, so that the mounting body 20 drives the position of the roller scraper 30 to be adjusted, thereby avoiding manual adjustment of the position of the roller scraper 30, thereby reducing the labor intensity of manual labor, and can improve the adjustment efficiency of the position of the roller scraper 30.

[0033] It should be noted that, in the embodiment of the present application, a plurality of first driving members 201 may be connected to the mounting body 20, and the plurality of first driving members 201 are spaced apart along the extension direction of the mounting body 20. In this case, the number of driving assemblies 40 may also be multiple, and each driving assembly 40 is connected to a second driving member 401, and the second driving member 401 cooperates with the first driving member 201. When the position of the roller-pressing scraper 30 is required, the plurality of driving assemblies 40 may be operated simultaneously, so that the plurality of driving assemblies 40 simultaneously drive the plurality of first driving members 201 to move through the plurality of second driving members 401, and the plurality of first driving members 201 simultaneously apply force to the mounting body 20, so that the rotation rate of the mounting body 20 can be increased, and the adjustment efficiency of adjusting the position of the roller-pressing scraper 30 can be further improved.

[0034] In addition, in the embodiments of the present application, Figure 1 As shown, the mounting body 20 can be rotatably connected to the rolling body 10 via the rotating shaft 001. With such a configuration, the mounting body 20 can be easily rotated relative to the rolling body 10. A rotating groove can be provided on the rolling body 10, and the end of the rotating shaft 001 is embedded in the rotating groove, and the rotating shaft 001 is fixedly connected to the mounting body 20, so that once the mounting body 20 is subjected to force, the mounting body 20 can move, thereby driving the rotating shaft 001 to rotate in the rotating groove, so that the mounting body 20 can rotate relative to the rolling body 10.

[0035] It should be noted that a mounting hole may be provided on the mounting body 20, the mounting hole penetrates the mounting body 20 along the extension direction of the mounting body 20, the rotating shaft 001 is provided through the mounting hole, and the two ends of the rotating shaft 001 are respectively embedded in the rotating grooves on the rolling body 10, so that the mounting body 20 is rotatably connected with the rolling body 10 through the rotating shaft 001. Of course, the rotating shafts 001 may be respectively provided at the opposite ends of the mounting body 20, and the rotating shafts 001 are respectively embedded in the rotating grooves, so that the mounting body 20 is rotatably connected with the rolling body 10 through the rotating shaft 001. This is not limited in the embodiments of the present application.

[0036] In addition, in some embodiments, Figure 2 or Figure 3 As shown, the first driving member 201 can be a gear, and the second driving member 401 can be a rack. The gear is fixed to the mounting body 20, and one end of the rack is connected to the driving component 40, and the gear is meshed with the rack; when the driving component 40 is running, the driving component 40 drives the rack to move along the extension direction of the rack, so that the gear rotates relative to the rack, and the mounting body 20 rotates relative to the rolling body 10.

[0037] Since the first driving member 201 can be a gear, and the second driving member 401 can be a rack, the gear is fixed to the mounting body 20, one end of the rack is connected to the driving assembly 40, and the gear is meshed with the rack. Therefore, once the driving assembly 40 is running, the driving assembly 40 can drive the rack to move along the extension direction of the rack, so that the rack will drive the gear to rotate relative to the rack due to the meshing effect with the gear. Once the gear rotates relative to the rack, the gear will drive the mounting body 20 to move, so that the mounting body 20 rotates relative to the rolling body 10, so that the rolling scraper 30 on the mounting body 20 will move with the rotation of the mounting body 20, so that the position of the rolling scraper 30 is adjusted. In addition, the gear is fixed to the mounting body 20, which can make the gear occupy a smaller space on the rolling body 10, and the meshing of the gear and the rack can also make the driving assembly 40 more efficient in driving the mounting body 20 to rotate relative to the rolling body 10. That is, by setting the first driving member 201 as a gear and the second driving member 401 as a rack, the driving assembly 40 can efficiently drive the mounting body 20 to rotate, and occupies a smaller space of the rolling body 10, which is convenient for setting components such as the driving assembly 40.

[0038] It should be noted that the gear can be fixed to the mounting body 20 by: the gear can be fixed to the mounting body 20 through a fixed shaft. At this time, once the rack drives the gear to rotate, the gear will drive the fixed shaft to rotate, and the fixed shaft drives the mounting body 20 to rotate. Of course, the gear can also be fixed to the mounting body 20 in other ways, for example, the gear is directly welded to the mounting body 20. The specific way of fixing the gear to the mounting body 20 is not limited in the embodiment of the present application.

[0039] In addition, in some embodiments, Figure 2 As shown, the gear may include a main body 100 and a plurality of gear teeth 200 disposed around the main body 100 . Along the circumferential direction of the main body 100 , the plurality of gear teeth 200 surround a portion of the main body 100 .

[0040] Through such an arrangement, when the driving component 40 drives the rack to move along the first direction, the rack drives the gear to rotate in the clockwise direction, and the multiple gear teeth 200 surround part of the main body 100, so that during the movement of the gear, once the gear rotates to the part of the main body 100 where the gear teeth 200 are not provided, the gear stops rotating; when the driving component 40 drives the rack to move along the second direction, the rack drives the gear to rotate in the counterclockwise direction, and the multiple gear teeth 200 surround part of the main body 100, so that during the movement of the gear, once the gear rotates to the part of the main body 100 where the gear teeth 200 are not provided, the gear stops rotating. That is, by setting a plurality of gear teeth 200 to surround part of the main body 100, the gear can have a range of rotation angles when rotating. Therefore, in practical applications, by setting the number of gear teeth 200 or the angle at which the gear teeth 200 surround the main body 100, during the rotation of the gear, once the gear rotates to a position on the main body 100 where no gear teeth 200 are set, the roller scraper 30 on the mounting body 20 can be directed toward the outside of the rolling main body 10, thereby facilitating the operator to repair or remove the roller scraper 30, or the mounting body 20 is rotated to this position, and the mounting position of the roller scraper 30 installed on the mounting body 20 is directed toward the outside of the rolling main body 10, facilitating the operator to install the roller scraper 30 on the mounting body 20, and then the gear is rotated in the opposite direction, so that the mounting position of the mounting body 20 is rotated to a direction toward the inside of the rolling main body 10, or the roller scraper 30 rotates to a position toward the outside of the rolling main body 10 as the mounting body 20 rotates. That is, by arranging a plurality of gear teeth 200 around a portion of the main body 100 in the circumferential direction of the main body 100, the stop position after the rotation of the mounting body 20 can be set, which is convenient for operators to repair or disassemble the roller scraper 30. The first direction and the second direction are both parallel to the extension direction of the rack, and the first direction is opposite to the second direction.

[0041] For example, Figure 6As shown, the driving assembly 40 drives the rack to move along the first direction, and the rack drives the gear to rotate clockwise. After the gear rotates to a position where the gear teeth 200 are not provided on the main body 100, the gear stops rotating. At this time, the installation position of the roller scraper 30 installed on the installation body 20 faces the outside of the rolling main body 10, and the operator can repair or remove the roller scraper 30 at the installation position, or install the roller scraper 30 at the installation position; then the driving assembly 40 can drive the rack to move along the second direction, and the rack drives the gear to rotate counterclockwise, so that the gear drives the installation position on the installation body 20 toward the inside of the rolling main body 10, and when the gear rotates to a position where the gear teeth 200 are not provided on the main body 100, the gear stops rotating. At this time, the roller scraper 30 is just in a suitable position to ensure that the roller scraper 30 can cut or adjust the battery pole piece.

[0042] Of course, in the embodiment of the present application, the gear may include a main body 100 and a plurality of gear teeth 200, and along the circumferential direction of the main body 100, the plurality of gear teeth 200 may surround the main body 100. The embodiment of the present application does not limit the specific form of the gear.

[0043] In addition, in the embodiment of the present application, the first driving member 201 can also be other types, for example, the first driving member 201 is a connecting rod, in which case there are multiple first driving members 201, and the multiple first driving members 201 are spaced apart and distributed on the installation body 20 along the direction of rotation of the installation body 20, and the second driving member 401 can be a push rod that cooperates with the connecting rod. The embodiment of the present application does not limit the specific types of the first driving member 201 and the second driving member 401.

[0044] In addition, in the embodiment of the present application, the driving assembly 40 may include at least one of a motor or a cylinder, wherein the motor or the cylinder are common components with driving functions and have low costs, thereby reducing the cost of the rolling device.

[0045] In addition, in some embodiments, the driving assembly 40 can be a cylinder, which includes a cylinder body 41 and a piston rod 42 connected to the cylinder body 41. The extension direction of the piston rod 42 is the same as the extension direction of the rack. Part of the piston rod 42 is located in the cylinder body 41, and the piston rod 42 located outside the cylinder body 41 is connected to one end of the rack. The piston rod 42 is used to drive the rack to move along the extension direction of the rack so that the gear rotates relative to the rack.

[0046] Since the extension direction of the piston rod 42 is the same as that of the rack, part of the piston rod 42 is located in the cylinder body 41, and the piston rod 42 located outside the cylinder body 41 is connected to one end of the rack, therefore, once there is gas in the cylinder body 41 to move the piston rod 42, the piston rod 42 will drive the rack to move, so that the rack drives the gear to rotate, and the gear drives the mounting body 20 to rotate relative to the rolling body 10, so that the position of the rolling scraper 30 is adjusted. That is, by providing the piston rod 42 and the cylinder body 41, it is possible to facilitate the movement of the rack, so that the mounting body 20 rotates relative to the rolling body 10, and the position of the rolling scraper 30 is adjusted.

[0047] It should be noted that in the embodiment of the present application, when the piston rod 42 moves in a direction away from the cylinder body 41, the piston rod 42 can drive the rack to move in a first direction; when the piston rod 42 moves in a direction close to the cylinder body 41, the piston rod 42 can drive the rack to move in a second direction.

[0048] In addition, in some embodiments, Figure 2 or Figure 5 As shown, the driving component 40 is a motor, and a screw rod 43 is connected to the output end of the motor. The extension direction of the screw rod 43 is the same as the extension direction of the rack. A slider 44 is sleeved on the screw rod 43, and the slider 44 is fixedly connected to the rack. When the motor is running, the motor drives the screw rod 43 to rotate, so that the slider 44 moves along the extension direction of the screw rod 43, thereby moving the rack.

[0049] Since the output end of the motor is connected to a lead screw 43, a slider 44 is sleeved on the lead screw 43, and the slider 44 is fixedly connected to the rack, once the motor is running, the motor can drive the lead screw 43 to rotate, so that the cooperation between the lead screw 43 and the slider 44 is equivalent to utilizing the principle of the lead screw 43 nut, converting the rotational motion of the lead screw 43 into the linear motion of the slider 44, so that the slider 44 can move along the extension direction of the lead screw, and the slider 44 can drive the rack to move, and then the rack drives the gear to rotate, so that the gear drives the mounting body 20 to rotate relative to the rolling body 10, and adjust the position of the rolling scraper 30. That is, by providing the lead screw 43, and the slider 44 is sleeved on the lead screw 43, and the slider 44 is fixedly connected to the rack, it is convenient to move the rack, and then adjust the position of the rolling scraper 30.

[0050] It should be noted that in the embodiment of the present application, when the screw rod 43 rotates clockwise, the slider 44 can move in the first direction, thereby causing the rack to move in the first direction; when the screw rod 43 rotates counterclockwise, the slider 44 can move in the second direction, thereby causing the rack to move in the second direction.

[0051] In addition, in the embodiment of the present application, the slider 44 can be welded to the rack, so that the slider 44 is fixedly connected to the rack. Of course, the slider 44 can also be fixedly connected to the rack by fasteners such as screws and pins. This embodiment of the present application is not limited here.

[0052] In addition, in some embodiments, Figure 1 As shown, the rolling device may further include a fixing frame 50, the fixing frame 50 is fixed to the rolling body 10, the driving assembly 40 is mounted on the fixing frame 50, and the fixing frame 50 fixes the driving assembly 40. By providing the fixing frame 50, the driving assembly 40 can be directly mounted on the fixing frame 50, so that the driving assembly 40 is convenient to be fixed.

[0053] In addition, in some embodiments, the rolling device may further include a controller (not shown in the figure) and a display panel (not shown in the figure), the display panel is arranged on the rolling body 10, the controller is electrically connected to the display panel, and the driving component 40 is electrically connected to the controller.

[0054] Since the controller is electrically connected to the display panel, and the drive assembly 40 is electrically connected to the controller, the operator can directly perform operations such as clicking and sliding on the display panel, which is equivalent to the operator sending instructions to the controller through the display panel, so that the controller controls the drive assembly 40 to operate, and then the drive assembly 40 drives the first drive member 201 to move through the second drive member 401, so that the installation body 20 rotates relative to the rolling body 10 to adjust the position of the rolling scraper 30. That is, by providing the display panel and the controller, it is convenient for the operator to operate the drive assembly 40 to adjust the position of the rolling scraper 30.

[0055] It should be noted that the display panel may be an OLED display screen, and of course, the display panel may also be an LCD display screen. The specific type of the display panel is not limited in the embodiments of the present application.

[0056] In the embodiment of the present application, since the mounting body 20 is rotatably connected to the rolling body 10, and the rolling scraper 30 is detachably connected to the mounting body 20, the mounting body 20 is rotatable relative to the rolling body 10, and when the mounting body 20 rotates relative to the rolling body 10, the rolling scraper 30 is driven to rotate, and the position of the rolling scraper 30 is adjusted. Since the driving assembly 40 is connected to the rolling body 10, and the first driving member 201 is fixed on the mounting body 20, the driving assembly 40 is connected to the second driving member 401, and the first driving member 201 cooperates with the second driving member 401, once the driving assembly 40 is running, the driving assembly 40 can drive the second driving member 401 to move, so that the second driving member 401 drives the first driving member 201 to move, so that the first driving member 201 drives the mounting body 20 to rotate relative to the rolling body 10, and the mounting body 20 drives the rolling scraper 30 to move, and the position of the rolling scraper 30 is adjusted. That is, in the embodiment of the present application, by providing a driving component 40, and the driving component 40 is connected to the second driving member 401, and the mounting body 20 is connected to the first driving member 201, the driving component 40 can drive the second driving member 401 to move, so that the mounting body 20 drives the position of the roller scraper 30 to be adjusted, thereby avoiding manual adjustment of the position of the roller scraper 30, thereby reducing the labor intensity of manual labor, and can improve the adjustment efficiency of the position of the roller scraper 30.
